I have a 36gal bow front that has been established for about 8-9 months so still new to fish. I have 5 platy, 2 sword, 2 black molly, 1 dwarf gourami and 5 tiny tetra fish (not sure what they are but about 1/2 inch long). My black molly I have had from a fry & as it has gotten bigger have noticed it has 1 bright blue eye. Is this some kind of birth defect or something wrong with her? i am in an area where we have hard water. PH is 8.2 (ranges 8-8.2 since have had tank), ammonia is 0, nitrites are 0 & nitrates are 10.
